Percentage lithology plotted against depth typify standard industry sample strip logs. While useful as a drill site record, logs with such a format have limited value for detailed subsurface interpretations. Now CRC has developed a method of logging cuttings that approximates core descriptions. In particular, our standard logs feature Dunham textures, lithofacies, 1-d cyclicity, photographic documentation of reservoir and source rock characteristics that are integrated with Gamma Ray, Density and Neutron logs.(example). Unlike the costly and discontinuous stratigraphic record provided by most cores, our cutting analysis creates a relatively inexpensive, continuous detailed stratigraphic record. Such logs are fundamental to more accurate stratigraphic and depositional models. They add value by mitigating ambiguity and uncertainty inherent in interpretations based upon remotely sensed petrophysical and seismic data sets such as FMI logs presentations, image logs, electrofacies and seismic attribute mapping..
